False
Which device will answer an ARP request?
The one that matches the target IP address.
The one with the correct MAC address.
The one that matches the source IP address.
The one that can process the ARP request.
Where is the ARP reply sent?
To the MAC address of the sender of the ARP request.

Yes
No
What happens when a MAC address is needed for a device that is not on the same network?
It uses the IP address instead.
